ISSUE
I have two forms:
frmFormsfrmDockRental
I have two controls associated with this issue:
lstOwnersonfrmForms(unbound)cboOwneronfrmDockRental(unbound)
The second form (frmDockRental) is opened using different listboxes located on frmForms (See Image).  I have one such listbox that's giving me grief.  It is a filtered list of contacts that when double-clicked it should be opening frmDockRental to a NEW record and set cboOwner, which is unbound, to a specific item in the list.  The same item listed in lstOwners from frmForms.
CODE
After a lot of fiddling, I came up with this - except nothing happens at all.
Private Sub lstOwners_DblClick(Cancel As Integer)
On Error GoTo lstOwners_DblClick_Err
    On Error Resume Next
    If (Form.Dirty) Then
        DoCmd.RunCommand acCmdSaveRecord
    End If
    If (MacroError.Number <> 0) Then
        Beep
        MsgBox MacroError.Description, vbOKOnly, ""
        Exit Sub
    End If
    On Error GoTo 0
    Exit Sub
    DoCmd.OpenForm "frmDockRental", acNormal, "", "", acFormAdd, acDialog, Me.lstOwners
    DoCmd.Close acForm, Me.Name
lstOwners_DblClick_Exit:
    Exit Sub
lstOwners_DblClick_Err:
    MsgBox Error$
    Resume lstOwners_DblClick_Exit
End Sub
And on frmDockRental, this:
Private Sub Form_Load()
On Error GoTo Form_Load_Err
    DoCmd.MoveSize , , 5.3 * 1440, 5.2 * 1440
'    If (IsNull(OpenArgs)) Then
'        Exit Sub
'    End If
    If Me.OpenArgs <> vbNullString Then
        Me.cboOwner = Me.OpenArgs
    End If
    If (Not IsNull(OpenArgs)) Then
        DoCmd.GoToRecord , "", acNewRec
    End If
Form_Load_Exit:
    Exit Sub
Form_Load_Err:
    MsgBox Error$
    Resume Form_Load_Exit
End Sub
I figured OpenArgs would be the best method to accomplish this, but it just doesn't work.  Nothing at all happens.  No errors, just nothing.

EDIT:
Here's an image of the step debugging.
